Getting Your Feet Wet With a Non Electric Treadmill If you want to try your feet on the water using a treadmill that isn't motorized, consider the NordicTrack Commercial X22i. This model is a hybrid that has an electric motor as well as an option for manual operation. They help you develop a proper running technique because they force you to land under your hips and engage the right muscles. They also react more nimbly to speed changes which makes them suitable for high intensity workouts. Manual
